Season 10 of American Idol featured two of the jazziest contestants the show has ever hosted: Haley Reinhart and Casey Abrams. The two growlers wowed audiences with their soulful performances, and their scat-tastic duet on “Moanin’ ” proved to be one of the highlights of the entire season.

Naturally, Haley and Casey didn’t want to let a good thing go, so they reunited to record the smooth Christmas classic “Baby, It’s Cold Outside,” which will be available for download on November 21.

You’ll have to wait until that day to hear the full track, but here on the Music Mix, we’ve got an exclusive 90-second preview of the seasonal anthem, which Abrams says “reminds you of the fireplace.” He lauds the track for being a “straight up a jazz standard” with “no four-on-the-floor bass drum.”

For the next 24 hours, give the sweetly sung song a listen below. After that, it’s gone!

UPDATE: Time’s up! Download the full song on November 21!

While speaking about “Baby It’s Cold Outside,” we, of course, had to ask Reinhart, who was signed to Interscope back in July, what she’s been up to out in Los Angeles (where, lets be honest, it probably isn’t cold outside). As expected, the 21 year-old wailer is hard at work on her debut album.

“I’m working my butt off right now,” she tells EW, “just getting in there with a bunch of different writers and producers every day.” Reinhart has already recorded a few tracks—including some that she wrote herself a few years ago— and she describes the sound of what she’s recording as “soul and R&B mixed, with some jazziness in there.” The singer adds, “You can hear the retro-ness, but it definitely has a modern twist. Hey—that rhymes!”

Reinhart thinks she’ll have new original music out sometime early next year, but for now, “Baby It’s Cold Outside” should tide over her eager fans. “I’m not going to make them wait that long!” she says, adding, “I’m really happy that I’m not having to rush this.” Her next step is choosing a debut single.
